Conductor vs goa: What are the differences?

Developers describe Conductor as "A microservices orchestration engine that runs in the cloud *". Conductor is an orchestration engine that runs in the cloud. On the other hand, *goa** is detailed as "A design driven approach for building microservices in Go". goa is a framework for building microservices in Go using a unique design-first approach. goa provides a novel approach for developing microservices that saves time when working on independent services and helps with keeping the overall system consistent.

Conductor and goa can be categorized as "Microservices" tools.

Some of the features offered by Conductor are:

• Allow creating complex process / business flows in which individual task is implemented by a microservice.
• A JSON DSL based blueprint defines the execution flow.
• Provide visibility and traceability into the these process flows.

On the other hand, goa provides the following key features:

• Creating a service with goa starts with the design. The goa DSL lets you describe the global properties, types and endpoints that make up the service API. The apidsl package docs provides a quick reference to all the DSL functions.
• Once the design of the API is in place goagen generates the corresponding data structures, validation code and handlers. Handlers are defined as interface methods. Implementing the service is thus as simple as implementing the generated interfaces.
• The best part about the goa DSL is that the engine is completely decoupled. Plugins can implement custom DSLs to extend the concepts described in the design. Plugins can also generate arbitrary outputs.

Conductor and goa are both open source tools. It seems that goa with 3.46K GitHub stars and 389 forks on GitHub has more adoption than Conductor with 1.9K GitHub stars and 571 GitHub forks.
